Abstract (en)
[origin: US2008088906A1] An apparatus includes a thin-film interference filter structure having a generally wavelength-dependent resonant response to incident optical energy in a predetermined range of wavelengths. The thin-film interference filter structure includes a thermally tunable layer having a thermally tunable optical characteristic such that a range of wavelength-dependent resonant optical responses of the thermally tunable layer are induced by a corresponding range of thermal conditions of the thermally tunable layer. The thin-film interference filter structure is configured to ( 1 ) receive a spatially varying pattern of thermal energy at the thermally tunable layer to impart a corresponding spatially varying pattern to the thermally tunable characteristic of the thermally tunable layer, and ( 2 ) receive the incident optical energy into the thermally tunable layer and output optical energy having spatial modulation corresponding to the spatially varying pattern of the thermally tunable characteristic.
